DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A recording material reproducing method and a recording material reproducing apparatus according to the present invention remove an image made of a thermoplastic or heat-fusible image forming material from a recording material such as plain paper. This is for reproducing a recording material such as plain paper. Here, as the method for forming an image comprising the thermoplastic or heat-fusible image-forming substance, there are electrophotography using a dry toner and a wet toner, heat transfer using a heat-meltable ink or sheet, hot melt. There are an ink jet method using ink, a printing method using an offset plate, a relief plate, and the like. In any of the above methods, a film-like image composed of an image forming substance having thermoplasticity or heat melting property is formed on the surface of the recording material. Here, the film-like image does not necessarily need to be an image covering the entire surface of the recording material, and is simply a water-based ink containing that the image forming substance does not penetrate into the recording material, and that contains a dye. 5 shows an image in a state where the image forming substance is not adsorbed on the recording material, as in the case of printing with.

The recording material reproducing apparatus has, for example, a belt-shaped peeling member, a belt-shaped sealing member, a conveying section, a pressing section, and a transfer section. The peeling member is a member having a higher adhesive force to the image forming substance than the recording material. The transport unit includes, for example, a transport roller, and holds the recording material between a peeling member and a sealing member that is paired with the peeling member, and transports the recording material while sandwiching the recording material between the peeling member and the seal member. Here, when the image forming substance is only on one surface of the recording material, the sealing member is for sandwiching the recording material with the peeling member.
It does not have to have high adhesion to the image forming substance. On the other hand, when removing the image forming substance on both surfaces of the recording material, a member made of the same material as the peeling member is used as the seal member.

The pressing section applies a pressure treatment or a pressure heating treatment to the peeling member and the image forming substance, and adheres the image forming substance to the peeling member.

The transfer section includes, for example, a sliding member made of a rigid body having a plurality of convex portions provided at a plurality of positions in the conveying direction of the recording material, on the side of the peeling member and the sealing member of the recording material. Have. The transfer portion slides alternately on the peeling member side and the sealing member side of the recording material sandwiched between the peeling member and the sealing member with respect to the convex portions of the sliding member side of the recording material on the peeling member side and the sealing member side. I do. When the recording material sandwiched between the peeling member and the seal member slides on the convex portion of the sliding member, the recording material sandwiched by the peeling member bends. When bending occurs, a compressive stress is generated on the convex side from the center of the recording material sandwiched by the peeling member, and a tensile stress is generated on the opposite side, so that a shift occurs between the image forming material and the recording material. Then, the image forming substances on both sides of the recording material are transferred to the peeling member. Thereby, the image forming substance can be removed from the recording material. Here, the convex portion of the sliding member on the peeling member side of the recording material and the convex portion of the sliding member on the sealing member side of the recording material mesh with a certain interval, and the transport amplitude D and the transport amplitude period L Satisfies the relationship of 0.01 ≦ D / L ≦ 10. This is D /
If L is less than 0.01, the recording material is insufficiently bent and sufficient stress is not generated, which may cause transfer failure of the image forming material. If D / L exceeds 10, recording may occur. This is because excessive stress is applied to the recording material and the recording material may be damaged.

Further, an image removal accelerating liquid composed of, for example, an aqueous solution containing a surfactant or the like is applied to the recording material after image formation, so that the image forming substance and the recording material can be easily separated. good.

Further, the image forming substance may be removed from both surfaces of the recording material by using a peeling member instead of the sealing member.

Further, the number of times that the recording material sandwiched by the peeling member is bent to the front side and the number of times that the recording material is bent to the back side are made the same.
The tensile stress and the compressive stress applied to the peeling members on both the front and back surfaces of the recording material may be the same. Thereby, the image forming substances on both the front and back surfaces of the recording material can be removed to the same extent.

As shown in FIG. 3, the transport unit 31 holds the recording material 10 having the image formed of the image forming substance 101 after the application of the image removing accelerating liquid, between the peeling belts 30a and 30b.
Transport. Here, the transport unit 31 includes, for example, tension rollers 31a and 31b and tension adjusting springs 31c and 3c.
1d, and the tension of the peeling belts 30a, 30b is made equal by the tension of the tension adjusting springs 31c, 31d.

The pressing unit 32 includes, for example, pressing rollers 32a, 32b, 32c, and 32d having a built-in heating lamp. The pressure rollers 32a, 32b, 32c, and 32d press or heat the recording material 10 sandwiched between the peeling belts 31a and 31b alternately from front to back. Here, the pressure roller 32

A roller covered with an elastic body such as rubber may be used.

The transfer section 33 includes sliding members 33a and 33b for sliding the recording material 10 as shown in FIG. The sliding members 33a and 33b are made of a rigid body such as a metal such as SUS. Each of the sliding members 33a and 33b has, for example, a rounded convex portion 331 at a tip portion.
The recording material 10 is slid with respect to. As shown in FIG. 5, the protrusion at the front end of the sliding member 33a on the back surface side of the recording material 10 and the protrusion at the front end of the sliding member 33b on the front surface of the recording material 10 have a transport amplitude of D as shown in FIG. And the transport amplitude period is L, 0.01
Satisfies the relationship of ≦ D / L ≦ 10. This is because if the D / L is less than 0.01, the bending of the recording material 10 is insufficient and sufficient stress is not generated, which may cause a transfer failure of the image forming material. Recording material 1 if exceeds
This is because excessive stress may be applied to the recording medium 10 and the recording medium 10 may be damaged.

The sliding members 33a and 33b have the same number of protrusions 331 so that the same tensile stress and compressive stress are generated on both the front and back surfaces of the recording material 10.

The spiral rollers 34a and 34b scrape off the image forming material 101 transferred to the peeling belts 33a and 33b and put the image forming material 101 into the image forming material containers 35a and 35b.

The drying unit 4 includes a drying drum 42 made of, for example, aluminum and a belt 43 having good air permeability and high surface smoothness. The recording unit passes through the image forming material peeling unit 3. The material 10 is dried, and the dried recording material 10 is discharged to the paper receiving unit 5. The drying unit 4 uses a roller pair with a built-in heating lamp 41 instead of a drying drum 42 made of aluminum and a belt 43 having good air permeability and high surface smoothness. Alternatively, a hot air fan or an infrared lamp may be used.

The operation of the recording material reproducing apparatus having the above configuration will be described with reference to the flowchart of FIG.

When the paper supply unit 1 takes out the recording material 10 having a film-like image composed of the image forming substance 101, the image removal accelerating liquid applying unit 2 sets the surface of the recording material 10 having the image,
Alternatively, the image removal accelerating liquid 100 is applied to both surfaces of the recording material 10 (Step S1). As a result, water permeates near the interface between the image formed by the image forming substance 101 and the recording material 10 near the surface of the recording material 10, and the recording material 10
Due to the difference in the amount of swelling between the recording material 10 and the image forming material 101, the recording material 10 and the image forming material 10
1 is easily separated. Here, the lower portion of the liquid take-out roller 24 is immersed in the solution receiving tray 23, and an appropriate amount of the image removal promoting liquid 100 in the solution receiving tray 23 is taken out.
The liquid take-out roller 24 and the liquid application roller 25
Thus, the excess image removal accelerating liquid 100 is squeezed out, and an appropriate amount of the image removal accelerating liquid 100 can be applied to the recording material 10, so that the recording material 10 can be prevented from being wetted more than necessary.

When the recording material 10 on which the image removal accelerating liquid 100 has been applied advances to the image forming substance peeling section 3, the transport section 31 of the image forming substance peeling section 3 sandwiches the recording material 10 between the peeling belts 30a and 30b. The recording material 10 is transported (Step S2). Since the recording material 10 is sandwiched between the peeling belts 30a and 30b, it is possible to prevent the recording material 10 from being damaged by friction or the like at the time of subsequent sliding. Here, since the tension of the peeling belts 30a and 30b is equalized by the rollers 31a and 31b pulled by the tension adjusting springs 31c and 31d, wrinkling can be prevented.

When the recording material 10 sandwiched between the peeling belts 30a, 30b advances to the pressing rollers 32a, 32b, 32c, 32d, the pressing rollers 32a, 32b, 32c, 32d.
Presses and heats the peeling belts 30a and 30b and the recording material 10 (step S3). By heating, the image forming substance 101 is softened and easily peeled off the recording material 10. Here, the pressure rollers 32a, 32b, 32
It is preferable that the temperature of the image forming substance 101 due to the heating of c and 32d is equal to or higher than the softening point of the image forming substance 101 and that the image forming substance 101 is not melted. This is because when the image forming material 101 is melted, the image forming material 101 on the recording material 10 is separated from the recording material 10 by the peeling belts 30a and 30a.
This is because it is difficult to transfer the toner to the peeling belts 30a and 30b without dividing the toner into b. For example, when a monochrome toner is used as the image forming substance 101, it is preferable to raise the temperature to a range of 60 ° C. to 140 ° C., particularly, a range of 80 ° C. to 120 ° C. Further, the peeling belts 30a, 30
By pressing the recording material b with the recording material 10, the image forming substance 101 can be adhered to the peeling belts 30 a and 30 b. Here, the pressure rollers 32a, 32b, 32c,
In the case of 32d, only the pressure treatment may be performed without heating.

When the recording material 10 that has been subjected to the pressure treatment or the pressure and heat treatment advances to the position of the sliding members 33a and 33b,
The course is bent at a predetermined angle in accordance with the plurality of protrusions 331 located at the distal ends of the sliding members 33a and 33b. Thereby, the recording material 1 sandwiched between the peeling belts 30a and 30b
0 moves in a zigzag manner while sliding on the sliding members 33a and 33b. In this manner, the recording material 10 is
By moving in a zigzag manner while sliding with respect to 3a and 33b, a gap is generated between the image forming material 101 and the recording material 10, and the image forming material 101 is separated from the recording material 10, whereby the image forming material 101 is separated. 101 to peel belt 30
a and 30b (step S4).
Further, as described above, the recording material 10 is moved by the sliding members 33a, 33a.
By proceeding in a zigzag manner while sliding with respect to b, the image forming substances 101 on both surfaces of the recording material 10 can be simultaneously transferred to the peeling belts 30a and 30b. Further, the number of the protrusions 331 of the sliding members 33a and 33b is equal, and both surfaces of the recording material 10 slide the same number of times.
The image forming substance 101 on both sides of the
a, 30b. Here, if the temperature of the image forming substance 101 decreases, it becomes difficult to remove the image forming substance 101 from the recording material 10 due to the anchor effect, and a defective removal may occur.
A and 33b may have a built-in heater to prevent the temperature of the image forming substance 101 from dropping.

The drying section 4 dries the recording material 10 from which the image forming substance has been removed, and discharges it to the paper receiving section 5 (step S).
5). Thus, the image forming substance 101 is transferred to the recording material 1.
Since the recording material 10 is removed from 0, the recording material 10 can be reused.

Here, in the above embodiment, the peeling member 3 is used for the sliding members 33a and 33b made of a rigid body having the convex portions 331 provided at a plurality of locations in the transport direction at intervals.
0b and the recording material 10 sandwiched between the seal members 30a to slide the image forming substance 101 on the peeling belts 30a and 39b.
Was transferred to a plurality of transfer rollers 33 as shown in FIG.
2a, 332b, 332c, and 332d are used to generate a stress on the recording material 10, thereby forming the image forming substance 101.
May be transferred to the peeling belts 30a and 39b.

(Specific Example) Next, an image is formed on both sides of a commercially available high-quality paper using a commercially available copying machine, and an image forming material is formed from the recording material using the recording material reproducing apparatus as described above. Here are some specific examples of removing.

In the specific example, the area of the image forming substance remaining on the reproduced recording material (commercial high quality paper) 10 is measured by image processing, and the measured value is used as the recording material before reproduction.

According to the present invention, as described above, a recording material is sandwiched between a peeling member and a seal member or a peeling member and conveyed. After the treatment, the image forming substance is adhered to the peeling member, and the carrier sandwiched between the peeling member and the seal member or the peeling member such that the transport amplitude D and the transport amplitude period L satisfy 0.01 ≦ D / L ≦ 10. The recording material is bent alternately on both sides at a distance in the transport direction to generate bending stress, causing a shift between the recording material and the image forming material, and transferring the image forming material to the peeling member. Therefore, it is possible to prevent the recording material sandwiched between the peeling member and the seal member from having insufficient bending stress to cause transfer failure, or prevent the recording material from being damaged due to excessive bending stress. .

Further, the recording material is conveyed while being sandwiched between a pair of flexible peeling members having a higher adhesive force to the image forming material and having a higher adhesive force with respect to the image forming material. After the image forming substance is adhered to the peeling member by performing the pressure treatment or the pressure heat treatment, the transport amplitude D and the transport amplitude cycle L
The recording material sandwiched between the pair of peeling members is moved in the transport direction so that the relationship of 0.01 ≦ D / L ≦ 10 is satisfied, and the same tensile stress and compressive stress are generated on the front and back surfaces of the recording material. Is bent alternately on both sides to generate bending stress, causing a gap between the recording material and the image forming material, transferring the image forming material to a peeling member, and holding the same with the peeling member. Insufficient bending stress occurs in the recording material, which can cause transfer failure, and prevent excessive bending stress from damaging the recording material. Image forming substances can be removed to the same extent.

Further, after applying an image removal accelerating liquid for accelerating the removal of the image to the surface of the recording material having the image, a peeling member is brought into close contact with the surface of the recording material having the image, and the recording material and the image are removed. Since the image forming substance is removed from the recording material after the adhesive force with the forming substance is weakened, the image forming substance can be more reliably removed from the recording material.
